Queen Anne declared war against France; additional troops were sent to Holland, and the Earl of Marlborough assumed the command of the allied army. The SIXTEENTH shared in the operations by which the French army was forced to retire from the frontiers of Holland; and they formed part of the covering army during the sieges of _Venloo_, _Ruremonde_, and _Stevenswaert_; took part in delivering the city of _Liege_ from the power of the enemy; and their grenadier company distinguished itself in the capture of the citadel by storm on the 23rd of October. The regiment afterwards marched back to Holland for winter quarters. [Sidenote: 1703] Towards the end of April, 1703, the regiment commenced its march towards Maestricht, and was in position near that city when the French army approached in order of battle, but did not venture to hazard a general engagement. The regiment shared in the operations by which the French were afterwards forced to make a precipitate retreat and take post behind their fortified lines. The services of the regiment were also connected with the siege and capture of the fortress of _Huy_, on the Maese river, above the city of Liege; and with the siege of the city of _Limburg_, situate on a pleasant eminence among woods near the banks of the Wesdet, which place surrendered on the 28th of September. After these conquests the SIXTEENTH returned to Holland. [Sidenote: 1704] During the winter six hundred men of the regiment joined the garrison of Maestricht, while the Dutch soldiers were working at the entrenchments on the heights of Petersberg: in May, 1704, the remainder of the regiment marched towards the Rhine, and was joined at Bedburg by the detachment from Maestricht. The Duke of Marlborough led his army from Holland to the heart of Germany, and, there encountering the legions of France and Bavaria, he gained two important victories on the banks of the Danube, and exalted the reputation of the British arms. The SIXTEENTH had the honor to share in this splendid enterprise, and to take a distinguished part in gaining the victory at _Schellenberg_ on the 2nd of July, when the regiment had Major Mordaunt, Ensign Charleston, one serjeant, and nineteen soldiers killed; Lieut.-Colonel Hamilton, Captain Coghlan, Ensign Key, one serjeant, and thirty-four rank and file wounded.
